..Er.. depends what you mean by 'Talyllyn' machines.....
If you are referring to the current single-line machines worked by the TR, then it is the same shade of red for the Pendre-Brynglas section - but the the visual similarity ends.
If, OTOH, you mean the ex-Talyllyn machines that are now in the Port - Minffordd section on the FR then, yes they are nearly identical ..but..
I fear to get the complete answer, I might need to post the photograph elsewhere - if I can call upon your good nature Mr. Coombs
- at the present moment, I think the following:
- undoubtedly, it is built by a contractor out in Argentina. Exactly what this means, I am not utterly sure in the case of the Railway Signalling Company (RSCo) - I suspect that unfinished castings and 'bits' were sent overseas and fettled/assembled in licensed workshops - rather than shipping over complete instruments.
- the design of the instrument is very, very peculiar. On the surface it looks a bit like an 'M' pattern carcass, but has more in common with the 'S' pattern. I say this on several counts - the galvo is the rather enormous type favoured by the 'M' pattern  (and evidenced on some British examples - LINK for the F configuration, 'M' pattern Boston Lodge intermediate, which I think is converted from a F config terminal instrument, formerly Wharf - Pendre [unfortunately, it shews what looks like an early 'S' pattern unpolarised galvo, fitted as part of the conversion to an intermediate])
- For comparison:
These are my own instruments (over in the country library), both 'S' pattern and set up for magneto working (sorry about the duff picture, off a mobile phone) - you can see the similarities with the Argentinian instrument.
I think on reflection the number 'S. 32'  and the lack of indicator in the top left of the instrument proves that this is an 'S' pattern instrument - I can't quite tell from the guideways in the picture - if so it is exceptionally interesting, as I think it is the lowest numbered 'S' pattern instrument I have ever seen. Coo.
 Fazakerley - the RSCo 'built' all the METS in the world - just in case later readers didn't realise..
 This is a potential pitfall - on some British and Irish 'M' pattern instruments the large galvo seemed to be favoured - but not on 'colonial' instruments - it all depends on when the instrument was constructed.
 As part of the licencing the numerical series was I think worldwide.
